Thick dust haze is expected across St.Vincent and the Grenadines tonight, with poor visibility and air quality due to a dense plume of Saharan Dust… Small-craft operators and persons with respiratory concerns should be aware/exercise caution as visibility and air-quality could be significantly reduced tonight with very thick haze (PM2.5 levels near 65 µg/m3 and PM10 levels near 140 µg/ m3).
Hazy conditions with varying intensity of dust concentrations can be expected into mid-week. Meanwhile, surges in the trade-winds could push showers and isolated thunderstorms across our islands by Sunday evening into Monday morning. Weak instability and a few showers could linger late Monday into Tuesday.
Moderate to occasionally fresh (~20 – 40 km/h) east south-easterly winds could turn easterly Sunday and increase to strong (40 – 50 km/h), with direction turning east north-easterly Sunday night, as a wind-surge crosses the island chain.
Moderate sea-conditions are across our islands, with easterly swells up to 1.5 m on western coasts and up to 2.5 m on eastern coasts…Small craft-operators and sea-bathers should exercise caution for reduced visibility and above normal swells tonight.
Conditions are expected to deteriorate by Sunday evening; with gusty winds, continued poor visibility and rough sea-conditions (swells near 2.0 m on western coasts and near 3.0 m on eastern coasts of SVG)…Swell heights could start falling Tuesday, returning to moderate (1.5 – 2.5 m) sea-conditions during the afternoon.
